Summary

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix slab-out-of-bounds read in hdr_delete_de() Here is a BUG report from syzbot: BUG: KASAN: slab-out-of-bounds in hdr_delete_de+0xe0/0x150 fs/ntfs3/index.c:806 Read of size 16842960 at addr ffff888079cc0600 by task syz-executor934/3631 Call Trace: memmove+0x25/0x60 mm/kasan/shadow.c:54 hdr_delete_de+0xe0/0x150 fs/ntfs3/index.c:806 indx_delete_entry+0x74f/0x3670 fs/ntfs3/index.c:2193 ni_remove_name+0x27a/0x980 fs/ntfs3/frecord.c:2910 ntfs_unlink_inode+0x3d4/0x720 fs/ntfs3/inode.c:1712 ntfs_rename+0x41a/0xcb0 fs/ntfs3/namei.c:276 Before using the meta-data in struct INDEX_HDR, we need to check index header valid or not. Otherwise, the corruptedi (or malicious) fs image can cause out-of-bounds access which could make kernel panic.

No network protocol is involved, and physical access is not required since the image can be delivered as a file, so Local rather than Physical.\nAC:L - The attacker fully controls hdr-\u003eused, hdr-\u003ede_off and the entry size in the crafted image, so the oversized memmove length is chosen deterministically and fires on the first rename/unlink of the crafted directory entry. There is no race, no timing window, and no dependence on memory layout to reach the corruption.\nPR:N - The attacker needs no account or privilege on the target \u2014 they merely supply the crafted NTFS image or removable device, matching the established scoring for this ntfs3 hostile-image class. Once the volume is mounted, plain directory-write access is all that is needed to reach ntfs_rename().\nUI:R - A victim (or an automount daemon acting on their behalf, e.g. udisks2 on USB insertion) must mount the attacker\u0027s NTFS volume, and a rename/unlink must be performed against it. This is the standard user-interaction requirement for crafted-filesystem-image bugs.\nS:U - The out-of-bounds access corrupts kernel slab memory within the same kernel security authority. No VM, sandbox, or IOMMU boundary is crossed.\nC:H - The memmove reads up to ~16 MB past the slab object, and the callers immediately persist the buffer back to the volume via indx_write()/mi_write(), writing adjacent kernel heap contents onto the attacker\u0027s image for later retrieval. That is a large, effectively unbounded kernel-memory disclosure primitive.\nI:H - The same memmove writes that attacker-influenced multi-megabyte length starting inside the index buffer, overwriting arbitrary adjacent slab objects with shifted heap data. Heap corruption of this magnitude is leverageable for control-flow hijack and privilege escalation.\nA:H - An unbounded ~16 MB memmove past a ~1 KB kmalloc object destroys allocator metadata and touches unmapped memory, producing the KASAN-reported fault and a kernel panic. The commit message explicitly states the corrupted image \"could make kernel panic.\""
